GEORGE W. EARL AND JAMES H. HAWLEY, OF KALAMAZOO, MICHIGAN.

IMPROVEMENT IN APPARATUS FOR REGISTERING GAMES OF BILLIARDS.

Specification forming part of Letters Patent No. 64,000, dated April 23, 1867.

To all whom it may concern:

Be it known that we, GEORGE W. EARL and J AMES H. HAWLEY, of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented a new and Improved Machine for Registering Games of Billiards, 850.; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a portion of this specification Figure 1 being a front view 5 Fig. 2, a top view; 'Fig. 3, a section in the line 00 0c of Fig. 2; Fig. 4, a section in the line 9 y of Fig. 2 and Fig. 5, a section in the line 2: z of Fig. 2.

The same letters refer to corresponding parts in all the drawings.

My improved machine for registering games of billiards, &c., is so constructed that it will register all the points of the game from one to one hundred, while it will also allow of the discounting of any portion of a game up to ninety-nine points. The said machine will also unerringly register the whole number of games played up to one hundred and fortyfour.

The actuatinghand A, which points to the marks and figures on the outer periphery of the portion R of the indicating-face, Fig. 1, is secured upon the end of the arbor B, that projects from the machinery out through the ceuter of said indicating-face. The arbor B is inelosed by the tubular arbor i, and the tubular arbor i is inclosed by the tubular arbor 0, as shown in Figs. 2 and 3. The pinion k on the inner tubular arbor 2' gears into the toothed wheel 1, which works on a pivot that is screwed into the front end J of the frame of the ma chine, and the pinion m, placed at the side of said toothed wheel Z, and permanently united thereto, gears into the toothed wheel a, which is secured to the tubular arbor 0. The indicating-hand which is secured to the projecting front end of the tubular arbor 2', points to the outer series of marks and figures on the inner portion S of the indicating-face; and the shortest indicating-hand, p, which is'secured to the front end of the tubular arbor 0, points to the inner series of figures on the inner portion S of the indicating-face. A knob projects from the front side of the actuating-hand A to facilitate the movements thereof. This hand indicates the successive points of a single game from one to one hundred. The hand j indicates the number of games that may be played from a half game to twelve games, and the hand 1) indicates the number of games that may be played from twelve to one hundred and forty-four.

At the termination of each game the bell H is rung by the joint action of the following parts-via, the cam F on the arbor B, the le ver f, projecting from pivoted and spring-actuated hub G, and the hammer at the end of the lever g, which also projects from the hub G.

Fig. 4 represents the aforesaid bell-ringing parts the instant before the actuating-hand A reaches the termination of a game, and Fig. 5 represents the said parts the instant after the termination of a game.

At the commencement of a game all the hands are brought to a vertically-pointing position, or pointing to 100 on the outer periphery of the indicating-face. A half-revolution of the actuating-hand A causes it to point to 50 on the outer periphery of the portion. B of the indicating-face, and this movement of the actuating-hand carries the handjto the dot between 12 and 1 of the outer series of figures on the inner portion S of the indicating-face, thereby indicating that a half of a game has been played and a full revolution of the actuating-hand A carries the hand j to l on the indicating-face;

and so onward until the hand j has been car ried around to the starting-point and the entire revolution of the hand j carries the point of the hand 19 from its starting-point to l2 0n the inner series of figures on the indicat-' ing-face, thereby causing both the handsj and p to indicate that twelve games have been played. Thus it will be perceived that twelve revolutions of the hand A will produce one revolution of the hand j, and one revolution of the hand j will produce one-twelfth part of a revolution of the hand 1;. g

The position of the respective hands A j 1), represented in Fig. 1, indicates that fifteen games have been played, and the further movement of the hands A and j to the position represented by the red lines in said drawing indicates the playing of fifteen and a half games.

The hand A communicates the afore-de' scribed movements to the hands j and 19, through the medium of the following parts, viz: The arbor B and the cam 0 upon said arbor,-the ratchetwheel E on the tubular arbor i, and the jointed draft-ratchet D pivoted tothe front end J of the machine. The said ratchet-wheel E has twelve teeth formed thereon at equal distances from each other. A half-revolution of the hand A from the starting-point causes the end I) of the cam O to raise the draft-ratchet D by pressing upon the descending rigid portion 01 of said ratchet, and thereby causes the hook at the lower end of the hinged pendent portion 6 of said ratchet to turn the ratchet-wheel E a distance equal to one-half the space between the points of two consecutive teeth on said wheel, or onetwcniyi'imrth part of an entire revolution of the same; and at the moment that the said movement is completed the tooth s on the face of the ratchet 1 drops down into contact with the abrupt side of a tooth of the ratchetwheel E, as shown in Fig. 3, and thereby prevents the imparting of a reverse movement of said wheel. The said half-revolution of the hand A carries the point of the hand j forward to the dot midway between the startingpoint and l on the indicating-face, thereby indicating the playing of half a game,'and the farther movement of the hand A causes the curved side of the cam O to farther and gradually elevate the draft-ratchet D until the extremity c of said cam attains its highest position, which position is-attained at the instant that the hand A reaches its startingpoint. This second elevation of the draftratchet D causes its pendent hook e to turn the ratchet-wheel E the remainder of the distance between the afore-mentioned teeth of said wheel; and the movement that will thereby be imparted to the tubular arbor i and the handj upon the same will bring the point of said hand to 1 on the indicating-face, thereby indicating that one game has been played.

The instant that the hands A and j reach the aforesaid positions, the curved rigid portion (Z of the draft-ratchet D will drop down on the rear side of the point a of the cam G, and thereby prevent the possibility of imparting a reverse movement to the hand A. At the same instant, also, the end of the spring-ratchet "r is sprung against the abrupt side of a tooth on the ratchet-wheel E, and thereby prevents the imparting of a reverse movement to said wheel, and by so doing it also prevents the imparting of a reverse movement to the hands j and p. At the same instant also that the hands A and j attain the aforesaid positions, the projecting point of the cam 1 passes from under the lever f, and thereby permits the spring a to vibrate the hub G to such an extent as to bring the hamrner at the extremity of the lever g into sharp contact with the bell H; and thus onward the operation'may be continued until one hundred and forty'four games have been registered by the machine. The friction-spring '0, Fig. 5, presses 011 the arbor B with sufficient force to temporarily retain the handA in any position in which it may be placed in the progress of a game.

vThe frame which contains the afore-described operative parts of our improved registering-machine may be composed of ends I and J, connected with each other by the rod K and the bottom plate L, in the manner represented in the drawings 5 or the said frame may be constructed in any desired manner.

The frame of our improved registering-machine may be connected with the rear side of the indicating-face of the machine by means of wood-screws passing through the apertures (d and b in the front end J of said frame, or in any other manner that may be preferred.

Having thus fully described our invention, what we claim therein as new, and desire to secure by Letters Patent, is

1. Combining the hand A, the arbor B, the cam (J, and the draft-ratchet D with each other, and with the indicating-face of the machine, in such a manner that while the points of a game, from one to one hundred, can be indicated by said hand, and a reversed movement be imparted thereto at, any portion of its revolution, short of an entire game, yet the moment that it passes said point a stop is interposed to prevent any backward movement of said hand, substantially as herein set forth.

2. The combination of the hand A, the arbor B, the cam O, the draft-ratchet D, the ratchetwheel E, the tubular arbor i, and the indicating-hand j, with each other in such a manner that the said hand j will indicate upon the face of the machine the number of games and halfgames played from a half -game to twelve games, substantially as herein set forth.

3. The combination of the hand A, the arbor B, the earn 0, the draft-ratchet D, the ratchetwheel E, the tubular arbor z', the pinion 7c, the toothed wheel l, the pinion m, the toothed wheel a, and the tubular arbor 0 with each other, and with the hand p, in such a manner that the said hand 19 will indicate upon the face of the machine the number of games played from twelve to one hundred and forty- -four, substantially as herein set forth.

In testimony that the foregoing is a full and true specification of our new and improved machine for registering games of billiards, &c.,

' we hereunto subscribe our names.
